I assume you refer to generation via Xpand? Basically you'll have to
load your model and perform an m2m transformation with one of the
available technologies, like xtend for example. You can configure a mwe
workflow to achieve this. I guess this is documented in the Eclipse help
for mwe.

As this question is not related to Xtext, I'll add the m2t newsgroup as
well.
